KNIFE FOR CUTTING SHOES Filed May 2, 1930 INVENTOR ATTORNEY Patented May 19, 1931 PATENT OFFICE OSCAR MICHAUD, F SALEM, MASSACHUSETTS KNIFE FOR CUTTING SHOES Application filed May 2, 1930. Serial No. 449,288.

My present invention has reference to what is commonly termed a knife for cutting shoes, that is, a knife for cutting the parts, which include the linings that constitute the upper of a shoe, and my invention is in the nature of a gage attachment for such knives, whereby different sizes of vamps and quarters including linings may be cut by a single knife from a single pattern.

A further object is the provision of an attachment for this purpose which shall be of an extremely simple construction, readily attached to the ferrule of the knife and 'having associated therewith gage discs arranged to the opposite sides of the knife and movable to contact with the strips to be cut by the knife, together with means for holding a desired number of such gage discs above those contacting the strips so that the knife can be held at a proper and desired distance from the edges of the pattern and whereby the parts constituting the shoe uppers may be cut in different sizes by the employment of a single pattern.

To the attainment of the foregoing the invention consists in the improvement hereinafter described and definitely claimed.

In the drawings:

Figure 1 is a side elevation of the improvement.

Figure 2 is a top plan view thereof.

Figure 3 is a sectional View approximately on the line 33 of Figure 1.

Figure 1 is an end view of the frame of the improvement.

Figure 5 is a plan view of one of the gage discs.

Figure 6 is a plan view of a pattern, the dotted lines indicating the cut made by the knife when a vamp or quarter of a determined size is required.

Referring now to the drawings in detail, the numeral 1 designates the handle of an ordinary knife for cutting shoes and the curved cutting blade which is secured to the handle is indicated by the numeral 2.

The knife is of the ordinary construction, and in carrying out my invention I arrange over the ferrule end of the handle and fixed 1y but preferably removably secure thereto the ring or collar member 3 of the frame of the improvement. From the ring or collar, which constitutes the body of the frame, there is extended side arms 4 which are ar ranged at upward angles with respect to the longitudinal plane of the handle and which have their outer ends formed with right angularly disposed downwardly arranged extensions 5. The sides of the frame are arranged at a suitable distance away from the sides of the knife, and the outer elements 5 of the frame are provided with upper and lower alining square or rectangular openings 6 and 7, respectively. Through these alining pairs of openings there are passed square or rectangular shanks of headed members, in the nature of pins or studs 8 and 9, respectively. The shank of the upper stud 8 has an opening therethrough in a line with one of the side members of the frame and through this opening there is passed the inner arm of a substantially U-shaped spring clip 10, the outer arm of the clip contacting with the outer end of the stud 8. The non-headed end of the lower stud 9 is threaded and has screwed thereon a nut 11 which contacts with one of the side members of the frame.

Any desired number of gage discs 12 may be employed but an equal number of such discs are arranged at each side of the knife 2. The discs also are of an equal size and thickness and each of the discs is provided with a central elongated slot or opening 13 of a size to receive therethrough the shanks of the studs 8 and 9.

A pattern from which the strips that constitute the upper of a shoe are to be out is disclosed by Figure 6 of the drawings and is indicated by the numeral 14. This pattern is for cutting the upper of a small size of a shoe and when the strips 15 that constitute the parts of the upper and the lining are positioned below the pattern and the pattern firmly secured thereon all of the gage discs are engaged by both the studs 8 and 9 so that the blade of the knife may be brought against the edges of the pattern. hen strips for the next size upper of a shoe are required all of the discs, except those directly adjacent the blade of the knife are retained elevated but the said inner discs are lowered so that they will have their lower edges contacting with the upper strip '15. This is accomplished by removing the studs 8 and 9 so that the mentioned inner discs may be lowered on the shank of the stud 9, theremaining discs being held elevated after the studs are replaced. By reference to Figure 3 of the drawings it willbe noted that the lower edge ofv the upper stud '8 is in contact with the upper periphery of the lower gage discs so that such lowered discs. are firmly sustained in proper-position. The discs, instead'of the f'klllYGS are now brought against theedges .of the pattern 14: in" the cutting operation.

arranging the discs on each side of the f knife a firm pressure against the strips 15 is afforded and in addition to this the knife may-be reversed for the "convenienceof the g operator in following the outline of the pattern during the cutting operation. When larger .sizesof Vamps or quarters and linings are required other discs arebrought to lowered position and thereby increasing the distance'between the edge of the pattern and the knife 2. Thus it will be noted that with my simple construction single patterns of 'a small size may be employed and also a single knife is used. forcutting the uppers ofany desired size of shoe.

Itis believed the forego ng description when carefully read in connection with the thesimplicity of my device and the advantagesthereof sothat further descriptionwill not vbe required. Obviously'l do notwish to be restricted to the precise details herein set forth and, therefore hold ;myself enfairlyfall within the scope of what I claim. Having described the invention, 1: claim: 1. A knife forcutting the uppers and linings of shoes, in which a patternof-adetermined size is arranged over the strips to be cut, of a framesecured to the ferrule of a knife handle and comprising upwardly @inclined sides; that merge into rightangular downwardly extended ends, upper and lower removable studs passed through the outer 7 ends of the frame, slotted gage discs supported by the studs,said discs being. adapted" to be selectively arranged onthe lower 55. and the discswhen on the lower stud being contacted by the upperstud.

stud or receiving both studs therethrough,

2. A knife for cutting theuppers and linings of shoes, in which a pattern of a determined size is arranged over the strips to be out, of a frame comprising a ring 7 member surrounding and fixed tothe ferrule .of the handle of the knife, upwardly inclined arms extending from the :sides of the ring member merging into right angularly selectively supported by both of the studs or supported by the lower stud and the discs when .on the lower stud being contacted by the upper studs.

In testimony whereof I afiizr my signature.
